Alaska earthquake

Alaska has more seismicity than any other region in North America and is by far the most seismically active state in the U.S with 24,000 earthquakes each year.
The biggest earthquake that ever struck Alaska was on March 27, 1964. Across south-central Alaska, ground fissures, collapsing structures, and tsunamis resulting from the earthquake caused about 139 deaths. It was the most powerful recorded earthquake in U.S. and North American history, and the second most powerful ever measured by seismograph; magnitude 9.2.
